PDF compression reduces the size of PDF images to make it compatible with web upload, printing, and email attachment processes. When your PDF file contains a lot of images with a large DPI such as 300, then the size of your PDF file could be very big. For example, 300 DPI is known as high resolution, and a DPI that is lower than 72 is considered quite low.Ī high DPI represents a high image quality, and also, a large file size. The DPI, or Dots Per Inch, of the images in the PDF file affects the size of that PDF file largely. The one important element that makes a PDF file big in size is the images in that file. But if you want to compress a PDF file while still keeping the original quality, it’s quite necessary to know what exactly is the element that makes a PDF file big. That’s why compressing a PDF file is necessary. The scale may be even wider depending on how much images are there in the document. A same document could be 30% - 50% bigger on a PDF file than on a Word document. PDF files can be exchanged and printed easily, so it’s very popular in the office.īut the file size of a PDF file could be one of the biggest drawbacks to your work efficiency. The format is used for saving files with the original formatting retained no matter what platform it is opened on.
